72V261LA20PF8

FIFOs Memory Overview

The 72V261LA20PF8 is a synchronous FIFO memory IC manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 16K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 50MHz and an access time of 12ns. It operates within a supply voltage range of 3V to 3.6V and is housed in a 64-TQFP (14x14) surface-mount package. The component is rated for commercial operating temperatures between 0°C and 70°C.

FIFOs Memory Feature Summary

• Supports single-clock or dual-clock operation for flexible system integration
• Includes programmable flags for status monitoring such as full, empty, and almost-full conditions
• Enables depth and width expansion for customized memory configurations
• Provides retransmit capability to maintain data integrity during bus cycles

FIFOs Memory Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling
• Telecommunications signal buffering

FIFOs Memory Procurement Notes

Verify the specific suffix PF8 confirms the tape and reel packaging format required for automated assembly processes. Confirm that the LA variant aligns with the intended 3.3V logic levels and temperature grade for the target application environment. Check current lifecycle status as discontinuation notices may affect long-term availability and sourcing strategies.

FIFOs Memory Selection Notes

Select this component when a unidirectional synchronous FIFO with 16K x 9 organization is required. Ensure the system design accommodates the 3V to 3.6V supply voltage range and the 64-pin TQFP footprint. Consider the 12ns access time and 50MHz speed against system timing requirements. Verify compatibility with existing clocking schemes for single or dual-clock operation modes.

FIFOs Memory Part Context

This part belongs to the 72V series of SuperSync FIFOs designed for low-power 3.3V applications. It serves as a functional equivalent to older 5V families while offering improved power efficiency. The device integrates standard FIFO control signals and status flags to simplify interface design for high-speed data buffering tasks in embedded systems.

FIFOs Memory Replacement Considerations

IDT72V261LA20PF8 is a verified alternate designation for this component. Verify pinout and electrical specifications match before substitution.
